Y Y 1 claim. (Creez-'52) My invention relates to improvements inclosures and has `forfone purpose the provision of closure means wherebya door may be moved into closed position prior to the actuation of thellocking means intended to hold/it: inv closed posi-- tion. Oneapplication of my invention is to rear closures for automobiles, but itwill be understood that a wide variety of other yapplications may bemade of the invention. One object is the provision of means forpermitting the closure of doors having yielding packlngs or pads orbuffers. Another object is the provision of means for moving a door intoclosed position prior to the movement of a, closing latch along an axisor in a plane generally parallel with. the plane of the door itself.Other objects will appear from time to time in the course of thespecificationv andV claim.

I illustrate my invention more or less diagrammatically intheaccompanying drawings,

wherein- Y Figure 1 is a sideelevation of a car, with parts broken away,showing the door in open position; Figure 2 is an edge view of the doorshown in Figure 1;

Figure 3 is a plan view of the door inA locked position; l

Figure 4 is a sectionV on the line 4-4 of Figure 2, showing the lockingunit separately, theparts being shown in unlocked position;

Figure 5 is a section similar to Figure 4, showing the locking unit inplace on theV door, the

parts being shown in locked position; Figure 6 is a section similar toFigure 4 on an enlarged scale;

Figure 7 is a section on the line 1-`1 of Figure 5; v'

Figure 8 is a section on the line 8 8 of Figure 5;

Figure 9 is a section on the line 9-9 of Figure 5;

Figure 10 is a top plan of a center locking bolt or tongue;

Figure 11 is a section on the line lI-I I of Figure 10; and

Figures 12 and 13 are diagrammatic views, illustrating the action of thelocking levers and locking bolt.

Like parts are indicated by like symbols throughout the specication anddrawings.

Referring to the drawings, I generally indicates the body of anautomobile, and 2 the rear car door hinged as at 3 by any suitableoffset supports 4. 5 indicates rubber padding around the door closure.Such padding or packing means,

preferably-yielding or elastic,l may be. applied Vtov the do'or frame orto the door or to' bothV as shown,

for examplain Figure 9. v Referring tofFlgure 9,1 theV door is shown asbeing'boinded by a framef which includes an inwardly turned' flanger.6', a-l

ange 1, and a' lip 8, the yielding packing or padding 5 beingV fittedinto the space bounded by the members 6,'1 and 8. Any suitableadditional re` inforcement may be employed shown in Figure 9 as anangle9, bolted in position as by the bolt I0 and adapted vto serve asabutment means for the door positioning locking means below described.

The door, generally' indicated as -2 in Figure 1, includes preferably Yasingle outer panel or surface member 2li.` The upper portionofthe'door,V

the body oi the door proper may be yformed in any suitable way, but Iillustrate an in ner door portion 2| provided with the flange 22 and alip or angleV 23 abutting against Vthe'inner face of the panel 2li at apoint somewhat short-of the lower edge of the door. The parts may bespot` Welded or otherwise secured together. In order to provide aconvenient positioning locking unit for the door which is readilyapplicable vto the door before or during the passage of the automobiledown the assembly line in the courseY of its manufacture, I` employa'species of panel or housing generally indicated as 25 which includes aflange 26 opposed to the flange 22, as shown in Figure '7, an inclinedportion 2l, and an additional portion 28 generally parallel with thedoor panel 20, and a ange 29 extending' from the portion 28 to the innerface of the door panel 20, to which it may be secured as shown in Figure'7. The member 28 is apertured as at 32 in line with the lockingstructure below de' and generally parallel with the member 28vis'abracketplate 33 which is formed at its ends with upturned anges 34which may be riveted or otherwise secured to the ends 3l of the panelhousing. This plate or support 33 has at one edge the upstanding flange35 which is secured to the front edge of the door which is formed atthat point by the member 29. This structure will be clear from Figure 7.

Mounted for rotation in the door panel 20 and the bracket or support 33is the handle 40 which. is provided with an enlargement or boss 4|abutting against the forward face of the panel 20, and a reducedcylindrical portion 42 which extends through receiving apertures in themembers 20 and 33 which apertures may be bounded by dotted line positionof Figure 9 to the active or press the rubber buffers or packings asshown in upset bearings 44, 45 respectively. A further reduced portion46 is screwthreaded to receive the nut 41 which, through theintermediary of the Washer 48, keeps the locking and actuating handle 40in position. The locking lever 50 itself is shown, for example, inFigure 10 and is well illustrated also in Figures 1 and 8. It has anupset portion 5I with an irregular aperture 52 therethrough. The portion46 mayr be formed, in cross section, to conform to the "aperture 52,

whereby to prevent relative rotation of the members 46 and 50. circularor cylindrical outer face seats..l ina. circular aperture 54 in thebracket 53, which bracket is secured as by a bolt or screw 53a to the Y'Y 'mobileit will be'understood that the top panel supporting member 33,as shown, for example", in Figure 8. It will be seen, therefore, thatwhile the nut 41 holds the parts together, when the nut 41 is unscrewed,as it can be through the associated parts can berernoved-and allthe-remaining parts are held in position.. It will bef understood,however, that when the parts are assembledv a rotation of .the handle 40will rotate also thelockmg lever 50.

Extending from `:the locking lever-'58 is a Apin 55 which hasrotatably,mounted/uponrit-,a stirrup 56. 51 is a rock shaft rotatablymounted upon the member 33. -It may, -for example, have integral bearingears struck` up at various points therealong as at 58 -or other ears 59which are mounted upon the plate or 'support 33. cent the ends of therock shaft are offset portions 60 the purpose of which will laterappear. An intermediate offset 6| passes between the stirrup 56 andthepin 55. It will be understood that when the handle 46 VVis rotated the c:orrespond-` ing rotation of V-the ,locking lever 50 will cause the rockshaft to rotate. Y This rotation will cause the offset portions 60,1;0move from the inactive locking full line position of Figure 9. In otherwords, a rotation of the handle 40 is-effective to force the fingers insuch position that they V draw the door inwardly againstthe door frameand Figure 9. When the door has beenmoved into closed position then, andonly then, is it possible for the locking lever 50 to move into fulllocking position. It is provided-with a projecting tongue or extensionWhichfis offset or beveled.

as at 66, to permit'it to ride over theA opposed locking abutment asshown at 61 in Figure '7. 68, 68 are stops `for limiting the movementofv the locking lever. When it is in unlocked :positionit engages thestop 68. When it is-in locked-,position it engaged the stop 69,referring to the position of the stops, for example, in Figures 4 and 5.It will be understood that the stops are `so located that when thelocking lever` 5U is vmoved,

Adja-I into locking position, it is held positively in locking positionby the elasticity of the rock shaft 51. In other words, the pin 55 movespast center. Apertures 16-16 are provided for the offset levers 60 ofthe rock shaft and the tongue 65 of the locking lever 50 projectsthrough the aperture 11 in the ilange 29 when in locked position.

In the operation` of the device, the lead of the members 60 over thelocking lever 50 is lsuch that door practically into full lockingposition, before the lol'sking= lever 50 rides over the abutment 61 intolocking position.

In the application of the device to an auto- 2l)` of the 'door isunbroken except by the aperture throughwhich the handle portion 42passes.

The door structure proper, which is compound, aperture 32, only thehandle 40 and its integrallyessary, V apart from whatever moldingv orspotl welding maybe necessary, is to insert the handle inposition,pplace the washer 48 in position` and run up the lock nut 41.

It ,will be realized .that whereasI have described a nd shown apractical and operative device,neyertheless many` changes may be .madein size, shape, number anddisposition of parts without departing Zfrom;the spirit of my invention. I therefore `wish my, description andshowing to betaken as ina lbroad sense lillustrative and diagrammatic yrather -thanas limiting me to' my specific showing.
